Thanks! I have a 30 gallon sump below the tank. The overflow drains through a filter sock, through carbon and phosban, past the skimmer and is returned using a 1350gph pump. After 4 foot head, the tank sees about 900gph, or about 12X per hour turnover. I have great flow, the corals love it. I'm looking at adding some baffled in the sump here shortly for a small fuge with a possible deep sand bed and some chaeto for additional nitrate export. I'm running T5's in the 10k range with actinic
Nick, Where's the chiller ? I made a BIG mistake when I set mine up by putting the chiller in the cabinet. Then I had to add (2) 110 cfm exhaust fans controlled by a thermostat to get the heat out of the cabinet. With the MH ballasts and the chiller the heat is unbeleivable in the cabinet. I'll snap some pic's later, but I think you saw my tank a couple of years ago. Dave
